766, filed September 22, 1922,1iow Patent No. 1,653,859.;5 w Thesupporting mjemberconsists of a pair of members 13 and 13? composed ofansuit-- able thin flexible material fsuchasbfi "reor muslin coatedbakelite which have extendin arms 14; and 14 and hasthe' metliod-offfastejning thesemeinbers13 and 1'3 jtothe tube tending cylindrical socketwall- 10 whose opening 11 is of a sizetofit a standard vac- ,uum tube.An orifice or bayonet slot12'is provided for engagement with a pinformed socketis similar in each case a description of one will .suflice.Thefinember 13 is of a length equal to thewidthof the tube socket, andorifices are provided near each end of the member 13 which when placedin position with the socketwill be! directly line with theorificesprovided in the lugs 4. Screws '15 are inserted inthe' orificesinthe lugs 4 i and orifices in the endsof thef inember 13.

Nuts, 16 whichhave screwthreaded engagemeiit with the screws 15 areturned down to] hold the socketand supporting member 13 I mo v -movement and collars 21, which are of a suitable height to keep thesocket from coming into contact with the baseboard 19, are pro.- videdto be placed on the screws 18 between the ends of the extensions 14 and14 and the baseboard 19. The extensions 14 and 14 are so designed that,when the supporting members 13 and 13 are placed in position with thesockets, the extension 14 passes under the member 13 and the extension14 passes under the member 13 and thus serve as added supports. Theseextensions 14 and 14 are so positioned in regard to the length of themembers 13 and 13, and are pitched at predetermined angles, and are ofsuch a length that the supporting screws 18, which are inserted in theorifices in the ends of the extensions 14 and 14, are in a verticalplane which is substantially at right angles to the tube socket. Thisplane which may be shown as the line pp in Fig. 3, passes through theexact center of the tube socket and consequently the weight of the tubesocket and of the vacuum tube inserted in it will be evenly distributedbetween the screws 18 and will cause the tube socket and tube to remainon an even keel. The extensions 14 and 14 are slightly flexible but ofsufiicient strength to support the tube socket. If for any reason theradio receiving set is jarred or moved the tube will not receive a quickjolt. and cause a distortion of sound, instead there will be nodistortion because the tube and itssocket are not rigidly supported tothe base. But the tube and socket will as a whole quiver or vibrate dueto the flexibleness of the extensions 14 and 14 which balance the tubeand socket. The jar will cause the tube to be unbalanced andthiscshifting of weight will cause the flexing of the extensions 14 and14. It will be readily understood by one familiar with the art thatthere is no sudden jolting of the tube when it is jarred but instead thetube is set quivering slightly and this quivering gradually slows up andfinally stops.

Figs. 5 and 6 illustrate a modified form of my invention. In this typeadiaphragm 121, composed of any suitable insulating material such asthin fibre or the like, equal in size and of the same size as the base 2of the socket is fitted against the peripheral edge2 2 of the base 2 andheld in position by means of screws 23, which extend through orifices inthe lugs 4 and diaphragm 121, and nuts 24 and lock nuts 25 which havescrew threaded engagement with the screws 23. A post 26 is secured to abase 27 by having a reduced portion 28 inserted in a suitable orificeprovided in the baseboard 27 and then spinning over the end of the post26 which rests in a countersunk portion of the base 27. The other end ofthe post 26 is inserted in a suitable orifice 29 located in the exactcenter of the diaphragm 121 and its protruding end 30 is inserted in awasher 31 and then spun over to hold the same in place and to supportthe tube socket as a whole on the post 26. The screws 23 are of a lengthsufficient to extend into orifices in the base 27 to prevent the tubesocket from rotating as a whole around the post 26.

When a vibration of any sort either mechanical or air wave istransmitted to the receiving set the tube and'socket, which are onlysupported by the post 26 which is in the exact center of the diaphragm121, will be unbalanced and started quivering due to the fact that thesocket is only supported at the post 26. The external conductorsconnected to the terminals of the socket being flexible to some degreedo not interfere with the supporting means taking up the vibrationstransmitted to the tubes.

Referring again to the structure shown in Figs. 1 to 4 inclusive, itwill be noticed that the arm 14 crossing the strip 13 causing the arm 14to be flexed down slightly, so that it is free from the lower peripheraledge of the socket as at 50. The same is true of the arm 14''. Thismethod of construction causes the socket to be yieldingly supported froma point near the center thereof.

While I have illustrated and described. a particular embodiment of myinvention it is to be understood that I do not desire to be limited tothe exact structure asshown and described, but intend to cover all suchchanges and modifications as come within the spirit and scope of theappended claims.

Having described my invention, what I claim as new and desire to secureby United States Letters Patent is:

1. A device of the character described comprising a tube socket, abaseboard, and a pair of flexible supporting members each having a mainportion and an integrally formed flexible extension arm adapted to passunder the main portion of the other member and provided with orificeslying in the same vertical plane adapted to engage screws to balance thesaid tube socket and to non-rigidly support the said tube socket inmobile relation to the said baseboard.

2. A device of the character described comprising a tube socket, abaseboard, a pair of flexible supporting members, flexible extensionarms integrally formed with said supporting members, said extensionmembers forming a yielding means of support for the member of which itis an integral part and also serving-asa means of su port for the otherof said supporting mem ers, and for the tube socket.

3. A device of the character described comprising a tube socket, abaseboard, a pairof supporting members eachhaving a mainportionyextension arms integrally formed-with said main portion ofsaidsupporting members and so arranged thatthe said arms extend parallelto each other and pass under and support the mainportion of the othersupporting member so that the said tube socket is non-rigidly andmovably supported on said baseboard at a substantially central point. v
